The utility model provides a technical problem to provide an ingot furnace cleaning device to improve the inconvenient problem of ingot furnace clearance among the prior art.
In order to solve the technical problem, the utility model provides an ingot furnace cleaning device, including attached in the ring rail of ingot furnace inner wall, install clearance piece on ring rail and with the dust catcher that clearance piece links to each other, clearance piece slidingtype install in just be equipped with the connection on the ring rail the dust absorption mouth of dust catcher.
Further, the annular guide rail is provided with a base part and a matching part connected with the base part, and the base part and the matching part form a T-shaped structure.
Furthermore, the cleaning piece is provided with a main body part and a pair of dust removal arms, and the inner side of the main body part is provided with a T-shaped groove for accommodating the matching part.
Further, the T-shaped groove of the main body part simultaneously accommodates the base part and the matching part, so that the main body part and the annular guide rail are mutually clamped and positioned.
Further, the dust suction port protrudes from the surface of the fitting portion for connection with the cleaner.
Further, the dust removal arm is integrally connected with the main body part, and the dust suction port is communicated with the dust removal arm.
Furthermore, the dust removal arm is provided with an inclined surface which extends from the main body part towards the inner wall of the ingot furnace in an inclined mode.
Compared with the prior art, the utility model discloses a mutually supporting of guide rail and clearance piece for the clearance piece can slide to different positions along the guide rail, thereby clears up the ingot furnace inner wall, can convenient and fast get rid of the impurity filth on the ingot furnace inner wall with the help of the effect of dust catcher, and the clearance time is short, does not hinder production, further improves the no miscellaneous environment in the stove, and then promotes crystal quality.
